Percutaneous electrolysis for the treatment of soft tissue injuries: scoping review

Abstract

Introduction: Percutaneous Electrolysis is an invasive physical therapy technique that generates a localized inflammatory process, promoting the repair and regeneration of damaged soft tissue. This technique has been internationally used and applied, often being combined with other physiotherapeutic interventions, thereby reducing associated symptoms and improving functionality in the studied populations. Objective: To map the use and application of percutaneous electrolysis in soft tissue pathologies for pain management and functional improvement as reported in the scientific literature. Methodology: A search strategy was implemented across PubMed, SciELO, Google Scholar, ScienceDirect, and PEDro, yielding a total of 185 articles. Five additional articles were manually identified. The selection process then employed title, abstract, and full-text screening. The variables of interest extracted from each article included “pathology”, “target tissue”, “electrolysis parameters”, “application frequency”, among others. Result: A total of 38 scientific articles were included. This study organizes the outcomes based on changes in pain and functionality in populations treated with Percutaneous Electrolysis. It has been suggested that this technique increases inflammatory markers, aiding pain modulation. This technique has been used in various pathologies such as temporomandibular disorders, rotator cuff tendinopathies, epicondylalgia, and plantar fasciitis, among others. Conclusion: Percutaneous Electrolysis emerges as a promising intervention, particularly for tendinopathies and painful syndromes. Percutaneous Electrolysis demonstrates significant effects in both pain reduction and functional improvement.
